The design of heart tattoos varies in shape, size and colors. Heart tattoo for couples on the wrist — thin line. Tattoo on the shoulder of the girl — heart and a kitten. Speaking of taking things to the next level, I have another option for you. This one falls in the latter category for sure. Charming tattoo heart with cute animals and flowers. Tattoo on the blade at the man — the heart, a dagger and an inscription.
